1. the extraction system of the invention designs two distillation pots which are connected in series, and designs a communicating pipe, a steam pipe, a communicating valve and a steam valve, and the two distillation pots can be connected in series or switched by reasonably controlling the communicating valve and the steam valve. In the application process of the extraction system, the distillation pot I starts to distill firstly, the steam valve I is cut off after the distillation pot I is finished, the heating device I is not closed, the distillation pot I continues to heat and distill, so that the residual hydrolat in the camphor tree raw material in the distillation pot I continues to be distilled, the communicating valve is opened, the hydrolat continuously distilled in the distillation pot I is directly merged into the distillation pot II, and the hydrolat continuously distilled in the distillation pot I and the oil-water steam distilled from the camphor tree raw material in the distillation pot II are collected together. Therefore, on one hand, the hydrolat and the essential oil in the distillation pot I can be distilled to the maximum degree, and on the other hand, the heat generated when the distillation pot I is continuously heated at last is reasonably utilized to heat the distillation pot II; and the first distillation pot is used as a standby pot after the first distillation is completed, the second distillation pot starts to distill, the second distillation pot and the first distillation pot are switched at the moment, and the process is repeated. The distillation method can completely distill the hydrolat in the camphor tree raw material. The equipment and the application thereof can not only reduce the loss of the hydrolat and improve the yield, but also fully utilize the heat and reduce the energy consumption.
2. The distilled water is directly heated by boiling water continuously to generate steam, so that the distillation time can be saved, and the extraction speed is accelerated; the distillation speed is high by adopting a water distillation mode, and the extracted hydrolat loss is less and the quality is good because the camphor tree raw material is not soaked in water of 100 ℃; the distillation pot is internally provided with the stirring device, the steam flow is increased through stirring, the distillation can be promoted, the distillation is more sufficient, the distillation speed is improved, distilled hydrolat can be prevented from dropping into water along with water drops, and the loss is reduced; the first-stage oil-water separator is provided with 5 outlets according to different types and different densities of camphor oil, wherein the top outlet leads out light oil, the bottom outlet leads out heavy oil, the other three outlets respectively lead out an oil-water mixture and crude hydrolat, the crude hydrolat enters a centrifugal device, the oil-water mixture enters a second-stage oil-water separator for oil-water separation again, and the obtained crude hydrolat is merged into the centrifugal device. The design can further improve the purity of the hydrolat and improve the utilization rate of the equipment. The centrifugal device comprises a first-stage centrifugal device and a second-stage centrifugal device, and the purity of the hydrolat can be further improved.
3. In the application process of the extraction system, the pretreatment step of the camphor tree raw material is designed, the treatment solution containing cellulase, polyvinylpyrrolidone, beta-mercaptoethanol and sodium chloride is adopted to soak the camphor tree raw material, and the cellulase can promote the dissolution of plant cell walls while improving the decomposition of cellulose and hemicellulose, so that more plant cell solutes are dissolved out; the polyvinylpyrrolidone can be combined with the phenolic substances, so that the influence of the phenolic substances on the hydrosol extraction is reduced; beta-mercaptoethanol is a reducing agent, and can effectively inhibit the oxidation of polyphenol and other substances; the pH is 4-5, so that the cellulase is suitable for survival and playing a role on one hand, and the acid can dissolve ash on the other hand; due to diffusion and osmosis, sodium chloride gradually permeates into cells through cell walls to cause concentration difference between the inside and the outside of the cells, so that the cells can absorb water and swell, and the hydrosol extraction is facilitated.
4. As can be seen from the data in Table 1, the cellulase, the polyvinylpyrrolidone, the beta-mercaptoethanol and the sodium chloride all have certain effects of improving the yield and the purity of the hydrolat, but the effect of the cellulase, the polyvinylpyrrolidone, the beta-mercaptoethanol and the sodium chloride when acting together is better than the superposition of the effects of the cellulase, the polyvinylpyrrolidone, the beta-mercaptoethanol and the sodium chloride when acting together, so that the cellulase, the polyvinylpyrrolidone, the beta-mercaptoethanol and the sodium chloride have the effect of improving the yield and the purity of the hydrolat synergistically.
5. According to the invention, the yield of the hydrolat is improved from two angles, on one hand, the cooperation between the two distillation pots of the extraction device can ensure that the distillation is more thorough, and the yield of the hydrolat is effectively improved; on the other hand, the cooperation between the first-stage oil-water separator and the second-stage oil-water separator of the separation device can further reduce the loss of the pure dew, so that the pure dew yield can also be improved. The centrifugal device is provided with a first-stage centrifugal machine and a second-stage centrifugal machine, so that the purity of the hydrolat can be improved.
6. The device has the advantages of simple structure, reasonable design, convenient operation, high extraction efficiency, low energy consumption, low cost and the like, is suitable for extracting the hydrolat and the essential oil of the camphor trees, can also be used for extracting the hydrolat and the essential oil of other plants, and has wide application value.
